<p>Secondly, define where to put all the modules in <b>_layout</b> variable, e.g.,<br>
<pre>
...
{i:'m301', c:'c1', t:'t3'},
{i:'m302', c:'c2', t:'t3'},
{i:'m303', c:'c3', t:'t3'},
...
</pre>
Wherein:
<ul class="bullet">
	<li><b>i</b> - short for id, the module ID</li>
	<li><b>c</b> - short for column, defines which column this module goes to, c1, c2 or c3</li>
	<li><b>t</b> - short for tab, defines the tab the module shall appear</li>
</ul>
